Weighted Bandlimited a calculation of rms noise

Hi all

I want to calculate the band including a weighted rms noise.   I'm able to calculate noise from rms to an analog signal without any bandwidth limitation.  Find the attached vi for details.  I want to limit the bandwidth to some known values (say 20 Hz to 20 kHz) and then calculate the rms noise.

Please advice.

Thank you best regards &,.

Siva

Siva,

What is the problem you are having?

I do not have the Sound and Vibration Toolkit, but when I replace it with a filter from the palette of Signal Processing, I get changes in bandwidth and in the calculation of rms.  The RMS.vi of the mathematics > probability & statistics palette produces the same value you use the VI of statistics. Based on average DC - RMS.vi Signal Processing > range of measures of waveform produced smaller values on the 3 orders of magnitude.

  • PCI-6110 - calculated resolution RMS

    We have a requirement for the resolution of measurement of voltage AC RMS. I am in a position a repetitive alternating signal with 512 samples on 1 cycle using the range full scale. I then calculate the value of these data. What is the effective resolution of the RMS measurement? Should not 512, 12-bit samples (signal varies for each sample) produce a measure of 12-bit resolution? How can calculate the actual resolution of bit RMS?

    I don't see how it takes into account the benefits obtained with various LSB errors between samples.

    The best I can determine via Google is the increase of the resolution for a simple average is the square root of the number of samples. So 512 samples would result in improved time 22.6 (adds 4.5 bits). The improvement of a quadratic average is probably different (less), but my test here with real hardware is in this stadium. Google also revealed that some applications intentionally add a small amount of random noise, resulting in a dramatic improvement in the calculation the resolution.

  • Re: Calculation of RMS

    Sorry for the use of this thread I can't find a way to post new problem.

    How amplitude and level VI calculates RMS calue for multi-frequency signals. For your unique, Vrms = Vpeak/sqrt (2) gives same result but for multi-frequency signals, is not match with 'amplitude and level measurement VI' calculated RMS. I need formula to calculate the effective value for calculations PAPR multi-frequency signal. I need RMS formula for multitone to apply the PAPR calculation in hardware.

    Attached code shows calculation of the PAPR by using different values of the RMS. Only calculation RMS Labview gives good results as comapare to "Vrms = Vpeak/sqrt (2).

    RMS = SQRT (SUM(X^2) (X) /sizeof)

    If only it turns out that for a full cycle of a sine wave, the RMS turns into Vpeak/sqrt (2).  For anything else, you must go through the full definition of the RMS to compute.

  • Calculation of RMS

    Hi all

    Please find the attached VI, I am computing the RMS for the first 20 values of amplitude. I want to reiterate this RMS calculation for every 20 samples until the end of the data samples. Suppose I have 1000 data samples, I should be able to draw on the graph of 50 points of RMS. Advice on how to go about it. Excuse me if I missed anything.

  • Calculation of RMS through a rectangular window with gap of time 25%

    Any signal (for example the sinuses), I need to calculate the RMS value, with an integration time of 1 millisecond , through a rectangular window, with a gap of 25%.
    In other words, instead of calculate an RMS value by considering every 1 ms interval, I need to calculate the value of a 1 ms window, then apply a gap of time 25% (of the window) and calculate the next RMS value assuming a 1 ms interval and so on.

    For example, in a 1 ms window, there is a 75% overlay.

    I appreciate all help.

    Thank you in advance.

    Hello.

    It has been long since I last posted something.

    I managed to get what I wanted, now I need to optimize it.

    I simulate a sinusoidal signal and I get a 1 MS integration time 't' just setting the number of samples n and the "fs" sampling rate (fs = N / t <=>t = N / fs). Can I use the tool "Extract the Signal Portion" and I calculate the effective value of the part in a loop.
    Anyone know if there is a way to do the same thing without the 'extracted signal part', because this tool using too much memory if the duration of the treatment is just too long with 4 k samples and 4 M samples/second.

    Thank you.

    Also, its worth noting that the formula should have 4 different conditions based on the way in which the user enters the information.

    You have your expression on the calculate event. This event fires when the form is loaded (and at this stage there is no value). I would wrap your expression around a condition that checks whether these fields are null. If they are null, then they have not been filled yet and you need to make the calculation.

  • Calculation of signal to noise ratio

    Hello.

    I was wondering if it was possible to calculate the SNR of a signal with LabView? I use a DAQ hardware and an accelometer to measure a force.

    Is that being said, possible to calculate SNR by looking at the graph of spectrum or vague? When there is no g on the accelerometer, there is a signal with a little noise... and I can see that in the spectrum of frequecny all the way to the cut-off frequency. What is the background noise?

    I'd appreciate any help!

    Thank you!!

    Abraham_E,

    Thanks for the data.  Curiously, the data do not seem to care what language you were using when you got it.

    The first data column appears as timing information.  The dt in who is 0.0005, which corresponds to a frequency of 2 kHz.  You said 400 Hz in one of your messages.  The discussion at the point 2 below corresponds to a frequency of 2 kHz sampling.

    1. you are right that SINAD is not very useful. SINAD assumes that all the power of the signal is the dominant frequency component that is not quite true for ECG.

    2. the size of the FFT of the signal shows the dominant signals at 50 and 100 Hz which is likely to be able to line with frequency. Al here also erase lines 200 and 250 Hz. You certainly do not want to calculate SNR under the assumption that the desired signal is 50 Hz.  The SINAD VI calculates the fundamental frequency than 49,97 Hz.

    3. If you don't know the 50 Hz and harmonic components, there is no obvious lines in the spectrum remaining. I interpret this means you have the significant variation of heart rate data.  This means that the heart rate is modulated in frequency. Frequency modulation broadens the spectrum.

    4. because there is not predominant in the spectrum, it is unlikely that frequency domain techniques will be worth any in the determination of the SNR.

    So, what can you do? Looking at the data graphic, I think a peak signal to noise power ratio could be significant. There are little noise, even at spikes, if it has a few problems too.  I have divided the data set in 1 second segments. For heart rate in these data, each segment contains one or two beats.  In each segment, I found the maximum and minimum values.  I set the value from Ridge to Ridge for the segment of the difference. I also calculated the RMS value for the entire segment. Then the SNR is the signal from Ridge to Ridge divided by the RMS value. It is probably more accurate to use the RMS value of the QRS and exclude parts QRS of the RMS of noise, but to do both is algorithmically and by the much more difficult calculation. It would be also better force segments contain exactly one beat of each. Again, it is much more complicated.  I then calculated the average of the SNR segment values and call it mean SNR.

    As I pointed out, there are some problems with the definition (peak to peak/RMS).  If you just want to compare signals within your lab to see which improves things, this should be good.  If you want to publish data and compare to other published results, you have to find how they define and measure SNR.

    In the attached VI I read the file once and recorded values in an array as a default value. Then I removed the file played screws and just worked with the data. To try this with other data simply insert read VI file in the appropriate place.

  • WIDTH of RMS in milliseconds

    Hello

    I have a question which I can not resolved. I used the function calls ChnRMS (XW, Y, E, RMSWidth) and users if they wish, can change the RMS width in percentage. But now they want to specify the width in milliseconds and I need a script for milliseconds in percentage change. What can I do?

    Thank you.

    Sara

    Hi Sara,.

    You can convert the time window in seconds to the window required in % with the following equation:

    L1 = NOC ("Time_Front")
    % = (CMax (L1) - CMin (L1)) * SampleRate_/100

    It would also be possible to create a custom dialog box that does this automatically and have your username jump to the top of this dialog box instead of the RMS ANALYSIS dialog box, but there is no way to customize the appearance or behavior of a function of ANALYSIS expedition.  We could take hostage the ANALYSIS icon for the calculation of RMS and have this call to the top of your custom dialog box, though.

  • JavaScript calculations "if".

    Hello

    I need assistance with a javascript calculation please. I work on the use of a weight to calculate the field "Ibu", but he would like up to a certain value. For example up to a maximum of 53.3 kg weight, the returned value would be calculated according to the weight multiplied by 0.375. In addition, the value will always be 20. How can I do this? The field reference is called 'Weight' and the calculation is weight * 0.375. I guess I would use one different 'If,' statement, but beyond that I'm totally clueless - have tried Googling, but I'm a bit desperate with java (I could do in a fundamental way back when lol).

    Many thanks in advance,

    Saqib.

    The custom for the field calculation script would be something like the following:

    (function () {
    
        // Get the value of the Weight field
        var v1 = getField("Weight").value;
    
        // Perform the calculation
        var  v2 = 0.375 * v1;
    
        // Set this field value
        event.value = v2 > 20 ? 20 : v2;
    
    })();
    

    This last line is equivalent to:

    if (v2 > 20) {
        event.value = 20;
    } else {
        event.value = v2;
    }
    
  • Solved: Too many minutes of exercise

    I had a problem with my Apple Watch save too of minutes of exercise:

    I went to the bottom of the tree to complete troubleshooting with the Apple support rep: turning Fitness followed under the privacy settings of fitness to & Motion off and on again; calibration data reset, turn the watch and the new matching and rematching of the watch.

    He seemed to work a couple of times, but a day or two more late the watch would go crazy once again, hundreds of minutes of exercise to record just by sitting still. I even sent the watch in for repair, but she came back with nothing appear on the diagnostics.

    It turns out that the problem was with my weight. The watch seems to use weights in his calculation of the exercise. I had put my weight when I created the watch, but I also used a workflow in the Workflow application for updating my weight for the purposes of health every morning. The problem was that the workflow was writing incorrect health app data (0.05 kg, for example). When the watch think you weigh only 0.05 kg, you get plenty of exercise sitting down just yet.

    If you are having problems with too much exercise minutes, open the application health and seek health data... Measurements of the body... Weight to ensure that the watch is not bad data that it uses to calculate your exercise badly.

    I hope this helps someone else!

    Thanks for the great info... I'm having the same problem.  quick question, you enter the weight through your phone/ipad correct application?

  • Measurement time 4132 SMU is too high

    Hello

    I use PXI - 4132 DC EMS to perform some DC measurements at high speed. I just took a 1 K Ohms resistance, forced 1mA and measure 1V. I have this done configuration and code completed. I get the correct measurements. But my problem is with the measurement time. The total duration is about 45ms to complete installation and measurement, with the exception of the 'initialize and close '.

    I checked the time at every step and I noticed that the maximum duration is taken during the "voltage reading. Out of the total 45ms, it takes about 34ms just for a measure. It's just a VI "Ukraine power measure" takes about 34ms, which is ridiculous compared to the Kiethleys. I tried to vary the time of "openness" and turn off the 'Auto Zero'. But the measurement time is still high. Can someone help me and let me know what is the best time of the measurement obtained with 413 x series SME?

    Thank you!

    Hey Phx_tech,

    The amount you reduce your delay source depends very much your HAD and how regular you have to your level of tension until you start taking your measurements.  If your Instrument is reactive, you can see discount gas and unintentional ringing during the transition from your output level and therefore would allow enough break-in before taking your measurement. The best thing to do is to experiment with different delays of source and see how much delay need you to get a consistent and reproducible measure. If you have a scope that is available, it will also show you the step response of the SMU with your Instrument.  If your first reading is higher than your other readings, that this could very well be a problem with not enough time settling.  What kind of DUT Testez_ you?

    From page 4 of the specification, you can see that 1 PLC, we can expect about 1 ppm RMS noise of the range to 1 PLC. This means in the range 10 au our measurement noise would be 10 pA RMS or 60 pA pk - pk.  However, your DUT + cables will pick up the extra noise and you should consider using wires of twisted shield pair to reduce noise picked up in your system.  The shield can be terminated at the mass of the chassis on the side EMS of the cable to help reduce noise appearing in your measurement.

    Let us know what you find after experimenting with you HAD.

    Thank you!

  • FPGA: update w / 14,4, fails w / Vivado 2013.4

    My FPGA code that compiled fine in LV 2011, then 2013 LV (using Xilinx 14.4). I didn't contact for some time...

    The upgrade to SP1 2014 LV, I believe that I have to re - compile to get the bit file to run on the target of the cRIO. However, now it does not compile. Cloud compiler error of timing. Clouds (local and compiler and elsewhere) report using Vivado 2013.4

    The code handles a moudle of analog input of series C 9205. 6 of the 32 channels are run by a calculation of RMS. A time loop is set to do this each 185 uSec (9205 card channels = minimum update 4uSec * 32 channels = 128uS = maximum theoretical to run the FPGA and to obtain valid data). Each value of 650 samples a new RMS is calculated.

    The rest of the channels get on average, 8 samples are averaged every 100th iteration of the loop above.

    The timing of the loop is a front panel control. I tried this increasing by 185 to 200 uSec, but it does not help. All inputs and outputs to the FPGA VI are written in / reading of the *(cRIO-9068) of host real time be using the controls on the front panel.

    This code has not changed in a very long time. I could share it if it helps.

    My questions around the investigate Center window timing results. Here, nothing seems useful. What is "path 1' and how is it related to the block diagram? View items and path are inhibited.

  • TL072 as a 1 MHz amplifier

    Hello

    I am using a TL072 as an amplifier with a gain of 10, and I can't seem to produce a sine wave output.

    I chose the TL072 because it worked well for me as a sinusoidal oscillator, so that it can handle 1 MHz.

    In the end, I want to put a sinusoidal signal of 1 MHz 2.1uV (pk) in the amplifier and he pulled out a sinusoidal signal of 1 MHz 21uV (pk). Can anyone offer a suggestion as to why I'm getting this output? Is the TL072 the correct chip for this? I have it connected properly?

    Any help would be greatly appreciated.

    JohnSym,

    I don't have a Multisim, so I can't look at your circuit, but I drew a certain circuits with amplifiers TL07x.

    1. the typical Gain-bandwidth product is specified at 3 MHz. This means that the open-loop gain is only 3 to 1 MHz.

    2. the specification of noise of entry is 18 nV/root (Hz) above 1 kHz or 4 uV on a bandwidth of 10 kHz.  For a bandwidth of 1 MHz, the noise density is 18 uV noise for entry.

    If you need more than three stages of amplifier for a gain of 10 to 1 MHz. consider four steps with a gain of 2.5 each. Entry to phase noise is of 18 uV. In the output, the noise is 45 uV. Do a sum of rms noise to the next stage of entry.  Its input noise is ~48.5 uV. Output noise is 121 uV. After the fourth stage, the noise is > 750 uV.

    This is not a device suitable for uV signals at 1 Mhz.
